IMPROVEMENT IN TYPE-WRITING MACHINES.

Specification forming part of Letters Patent No. 207,002, dated August13, 1878 application tiled April 19, 1878.

To all whom it may concern:

Beit known that I, ERNEST It. BARRON, of Ilion, in the county ofHerkimer and State of New York, have invented Improvements inType-Writing Machines, of which the following is a specification:

rIhe invention relates to the paper movement of a typewritin g machineaudits nature Vis in combining a shield With the carrying-band, incombining a guide-shield With the bandpulley and carrying-band, and incombining the reversed scale with and attached to the carrying-bandguide-shields.

The accompanying drawing and following description. thereof fullyillustrate the invention.

Figure l of the drawing represents a view ot' the under side of thepaper-carriage, with the hinged linger and guide-shields attachedthereto; Fig. 2, another view ofthe platen, band-pulleys, carrying-band, and guide-shield Fig. 3,a View of the reversed scale attached tothe'guide-shields, and Fig. 4 another view of the guide-shield.

In the drawing, A represents the top plate of the main frame of atype-Writing machine; B, a lug extended up from each lateral edge of thetop plate, A; C, a hinge and guiderail attached to the lugs B, acrossover the hind part ot the top plate, A; D, a papercarriage, adapted toturn as a hinge, and to run on Wheels on the hin ge-rail C; E, acylindrical platen across and iu journal-bearings in the side bars ofthe carriage D 5 F, a pressure-roller across and in slot-bearings in theSide bars of the carriage D; G, a round rod attached to the side bars ofthe carriage D, across in front of the platen E 5 H, a pulley, loose oneach end of the pressure-roller axle F, and on each end of the axle-rodGr; J, a carrying-band under the platen E, and around each twocorresponding pulleys H; K, a bifurcated guide-shield attached to theaxle-rod G, astride each band-pulley H, and extended back under thecarrying-band J, and longitudinallyin the upper side of which back ofthe forks, is a groove, or a longitudinal flange is extended up fromeach lateral edge, between which anges or in which groove the carrying-band is adapted to pass; L, a reversed scale attached across to thehind cud of each guide shield K, and M a curved `n ger attached to theaxle-rod G, and extended back under the platen E, and adapted to turnon. the axle, to press up against the platen, and to bc taken oft'andput on and ad j usted thereon.

The front band-pulleys, H, are liable to slip to the right or left alongon the axle G, and tl'lereby.` throw off the Carryingbands J 5 but theguide-shield K, which embraces each front pulley, with a part on eachside, guides and holds the latter in place, while the grooves or lianges help guide and hold the carryin gbands in place.

rIhe hiking-ribbon, which passes over the top plate A, longitudinallyunder the platen E, will4 touch and ink the carrying-bands J, which, inturn, will ink and crock the margins of the paper Written on; but theshields K prevent the contact of the ribbon with the bands, and thusprotect the paper from soiling.

The hind ends of the guide-shields K make convenient places to which toattach the ends ofthe reversed scale L. Therefore,

IVI] at I claim is as follows:

l. The combination of a shield with the carrying-band of a typewritingmachine, substantialltvT as described.

2. The combination of a guide-shield with the band-pulley andcarrying-band of atypewritin g machine, substantially as described.

3. The combination of the reversed scale with and attached to thecarrying-band shields of a type-Writing machine, substantially asdescribed.
